Unmatched Performance on the Strip for Stock GM Front Ends

QA1 ''R'' Series Drag Racing Kits are designed to transform your stock GM front end into an extremely efficient drag race system. This easy, bolt-in kit requires minimal modifications and works by replacing the factory shocks and springs with the QA1 ''R'' Series Pro Coil System. "R" Series have rebound and compression adjusted together on one knob with 18 clicks and stiffer compression valving. A looser rebound in the front allows weight to transfer to the rear when launching and a firmer compression keeps the front end from slamming back to the ground. The conical springs are designed so the lower end sets on the coil-over shock and the upper end sets in the original spring bucket. This allows for the use of a longer and lighter spring which translates into better weight transfer. Also the ride height is adjustable by use of the aluminum threaded body of the coil-over. Made in the USA

The Pro Coil System Includes:

Two Drag "R" Series single adjustable coil-over shocks

Two specially designed conical springs

All mounting hardware.

Easy Bolt-In Installation - Minimal modifications to be made. Remove the existing shocks and springs and the QA1 Pro Coil System bolts right back in.
Ride Height Adjustable - Threaded aluminum shock body allows ride height adjustment.
Specially Designed Conical Springs - This spring is designed so that the lower end sets on the coil-over shock and the upper end sets in the original spring bucket in the frame. This allows for the use of a longer and lighter spring for more stored energy, offering increased weight transfer. Greater durability is also achieved by locating the spring pressure in the frame and not on a single stud.
